Disengagement vs. Tumbling Evasion?

By Mungo4, in Dark Heresy Rules Questions

Hi,

What is the difference between the Acrobatics Actions "Disengagement" (as described in the Core Rulebook) and "Tumbling Evasion" (as discribed in the Inquisitor's Handbook)?

Disengage: you may make an Acrobatics Test to reduce a Disengagement Action to a Half Action

Tumbling Evasion: disengage as a Half Action, your opponent gains no free attack on a success. On a failure you still move but opponent gets a free attack with a +10 bonus.

And why is there a free attack mentioned at all in Tumbling Evasion as the Disengage by definition negates a free attack?

As I understand it :

- Disengagement : 1full action, no free attack, plus you may make an Acrobatics test to make it an half action instead of a full action (which also means that, in case you fail the test, you still desengage but it's still a full action)

- Tumbling Evasion : 1 half action, make an Acrobatics test. Succes means no free attack. Fail means opponent gets a free attack with a +10 bonus. gui%C3%B1o.gif

By the RAW, Tumbling Evasion seems less interesting that Disengagement.

This leads me to think taht, by the RAW, too, you can't disengage if you already make one half action that turn, unless you make, in fact, a Tumbling Evasion.

Example :

Bob is trapped in melee.

It's his turn.

He chooses to disengage.

He makes an Acrobatics test, but fails.

So he disengage, but as it's a full action, he can do nothing more this turn. gui%C3%B1o.gif

Whereas Bill, his friend, who is fighting the same ennemy, make a standard melee attack, on his turn.

He still can perform a half action.

He want to disengage too.

But he can't because it would be a full action.

So he can only try a Tumbling Evasion. happy.gif

Thanks, makes a lot of sense.
