Hello friends. Yesterday when we got beaten by Tog-Sothoth my friend drew a spell that when used could awaken the Ancient One straight away. Beeing a failry decent Arkham Horror player I could not really understand the use behind this..

The card I am referring to is NOT "Call Ancient One" as then you would be able to remove doom tokens, but another card with the name of a chant or similar. Could not find it in the Arkham Horror Wiki though...

I think this is the card you got:

javascript:void(0);/*1327907114962*/

Anyway, if might be advantageous as a latch- ditch effort (if you know you're going to fight it anyway) if the Ancient One gets stronger over time (for example, Hastur with the Terror limit)

Yep, that's the one I was referring to. Now that you mention it Hastur could be such a case, and also Eihort might be a good idea to call upon if your are prepared and doesn't have that many brood tokens. Thanks for the answer...

It's very situational and never something you want to be contemplating using, but it has its uses.

There are plenty of situations in which you might think "we're better at combat right now than we will be in a few turns". The obvious example is Blessings: if the doom track is right on the brink, and everyone has been Blessed by a Mythos card (or similar), it'd probably be better to fight the AO right away, rather than risk losing the blessings and THEN have to fight.

The Massa di Requiem can also be used to threaten someone who is attempting to "Join the Winning Team". In theory anyway.

Unfortunately, both can be used to rock Hastur immediately, so a revised version of Hastur was made that includes a flat -5 to combat checks.

Yeah, something like thecorinthian said... also, Yibb-Tstll's modifier gets worse with more clues on the board, so if you manage to clear most or all of the clues and then suspect that you'll wind up fighting anyway, that would be a good time to use the spell.

Gear up and awaken Glaaki asap.
