The short answer is: Sort of.

The longer answer is that the English translation of Anima is terrible, absolutely terrible, at distinguishing between "energy-based attacks" and "ENErgy attacks" which are, unfortunately enough, two different things. Two very different things at times, although they do overlap.

Thinking this would be one of those cases, I checked the Spanish Core Exxet and it reads " El individuo u objeto designado se vuelve completamente invulnerable a cualquier daño que no sea capaz de afectar energía" (CE 191) which, roughly translated, means "The designated individual or object becomes completely invulnerable to any damage without the capacity to affect energy."

This is an extremely important distinction, because fire, cold, electricity, and energy are all 'energy-based' attacks and can, therefore, affect energy. Also, those with Presence Extrusion are capable of affecting energy. So, in short, yes, you could survive a rockslide and not take any fall damage, but fire would still burn, and a well-trained warrior could still kill you.

To look at it another way, if it were complete immunity to anything that doesn't attack on the Energy AT, the spell would be one pretty much every player-made wizard would pick up immediately and maintain for the rest of their lives because, well, there aren't a lot of attacks that actually hit the Energy AT, and it's only a 10 Daily maintenance. Talk about god-mode for free...

Hope this helps!

I really appreciate the answer, and while not as powerful as I thought it would be definitely still going to take it just to jump off a cliff and take no damage.

fire, cold, electricity, and energy are all 'energy-based' attacks and can, therefore, affect energy.

Are you sure of this? It's possible with cold affect an intangible being?

Fully certain of the first part, yes. Though the last bit is perhaps best answered "yes, but not as easily as one might think."

There are a few scattered sections which seem to go back and forth at times on what exactly can or cannot damage energy and intangible beings and all of that. One of the first sections to deal with it is from page 93 of the English Core:

Energy Attacks: These attacks have no physical substance. Since the power that forms them is not really tangible, a normal individual is incapable of blocking them. Logically, if someone can not touch energy, he would have a serious problem stopping an attack made from it. His Block Ability would be of no use, since there is nothing he can put in between himself and the attack. In such a case, the natural reaction would be to Dodge it, since Block is automatically reduced to zero. A character can Dodge Energy Attacks with no additional penalty beyond the difficulty of Dodging Fired projectiles.

Remember that there is a big difference between Energy Attacks and those attacks that can damage energy . Many intangible supernatural beings, or those with special protection, can not be affected by attacks that can not harm energy. For that reason, a combatant must have a magical weapon or Ki Ability to hit supernatural bodies. Although these weapons can damage intangible beings , they themselves are tangible, and therefore can be blocked by normal weapons without any penalty. By Energy Attacks, we refer to intangible magical discharges or similar effects that can pass through any material body to reach their objective.

Some magical weapons have a Secondary Energy Attack Type (or a Heat, Cold, or Electricity one), but continue to be of a material nature. In such a case, even if it is possible to force an opponent to use his armor’s Energy AT by using a Secondary Energy Attack Type, the defender can still Block these attacks normally.

It is worth making special mention of attacks made with Electricity, Cold, or Heat, since in a more limited way, these can also be difficult to Block. If someone attempts to Block one of these attacks, such as an igneous discharge, a penalty of 120 applies to his Ability for not being able to Block Energy. Once again though, there are no added penalties to the Dodge Ability.

The italicized sections are my own, just to highlight a few things. Even in Spanish, the section basically says the same thing, which is highly unfortunate. The passage indicates that Heat, Cold, and Electricity attacks are energy attacks (since they're included in the section) but they're not as intangible as pure energy. Energy-based attacks can't be blocked, and yet the secondary Heat/Cold/Elec can be blocked and are based on energy because they require the ability to block energy to remove the huge penalty. So... they're only sort-of based on energy? Confused yet? So are many people who approach Anima. What makes things a little worse is, perhaps, this quote from the Magic chapter of the Core on page 114:

Only attacks on the Energy AT are capable of damaging immaterial beings or those immune to non-Energy based damage. As magical as it may be, a fire ball will not harm a specter; a more spiritual attack is needed for achieving this task.

Which seems to contradict the passages above. It's magical, it's energy-based, but it's not the right kind of magical energy-based? What in the world is going on here?

So, we hope on all the way down to page 283 where Spirits and Souls are actually discussed to find...

Contrary to what the name might suggest, the souls are not only ghosts or spirits of beings that have passed away, but also entities that belong by their nature to the spiritual world and who lack a physical form . They are unique creatures that cannot reproduce by any means and whose birth is due to very concrete events. This would be the case of many various entities – forest spirits, living nightmares, souls in sorrow, etc. The creation of souls is the same to that of Beings Between Worlds, although they possess certain special particularities. First, the souls are intangible by nature and they cannot touch or be touched by bodies that are not based on energy or that cannot harm it. They are invisible to everyone that does not have the ability to see spiritual beings or isn’t able to detect their energy, and they innately possess the Essential Ability Physical Exemption. Given that they lack a material form , they use their Power characteristic to calculate their Life Points instead of Constitution (or rather, both attributes are the same with souls).

Here we find something akin to an answer to the problem, but only when combined with the first few sections. Heat, Cold, and Electricity lie in a realm known as "energy-based attacks" but they are, for all intents and purposes, physical energies. In order to interact with the body they need to have a physical contact with the person, and so, therefore, they can't affect beings which lack a body or physical form. Physical Immunity gives you immunity to physical damage not based in energy, but it does not remove your body, so physical energy can still smack you down. An intangible being lacks that same condition, and so cannot be affected.by fire even if that fire was magically conjured, because the fire is just normal fire after it springs into life. It's not magical fire, it's not pure-energy fire.

In short: Yes, and then yes with conditions.

I hope this helps, and happy gaming!

Thanks, I asked because of Energy Discharge Psychic Power, which can affect immaterial beings only from a certain level.

Fair enough. Anima is a confusing place at times. Even I have questions I haven't gotten answers to, though not for lack of trying.

Oh, what about the Ebudans?

Can Celestial Essence be bieaten by fire or cold, or only by energy?

Since the Ebudan don't become immaterial once achieving their Sue'Aman, they've still got to contend with such things. It's still a nice way to wade through the masses though.
