Ok how about the fix I assumed Rage worked.
Which is that it only works with normal attacks and not skills.
You can even lower the AP cost in that situation... sure it is powerful, but not all powerful.
Rage is a status of mind coused by a stress. External condition.
Mechanics who activates rage on demand is wrong since beginning.
Rage should rather stance, or a long term buff.
When you get hurt then the real rage is activated.
Also, in the state of mind rage the person refuse rest of the world. So, the attack action who activets rage should be nulified. Even spell, even cc.
B:I have chopped off your arm.
A: Aaaaaggggr , I'am going to rip off your head.
B: But, ... but .... but you dont have arms.
<head is rolling>
So the game mechanics >>>
1AP state rage (ability skill self, stance mechanics - same as power stance from DOS1)
When you get hit (by anything harmful) you have a chance 20% to get status rage. (attacks which cause several effects are counted as one rage roll chance)
The attack or a spell which activates rage doesnt have any affect at all. e.g. no dmg, no cc applied. Just ignored.
The raged person gets immediate free rage attack. (see bellow)
Status rage lasts 1-2 rounds. random
Basic melee attack is available.
Battering ram skill is available.
Ranged weapons, skills, spells, scrolls, consumables are not available.
On performing basic attack its 10% to get another free rage attack.
Free rage attack - another target in 2 m range is selected randomly and hit. Could be anyone. e.g. even friendly character. If there is no other target available in range, then the original target get the hit.
That is the badass rage :]
