Apologies for the double post, but to continue my learning on this class, let´s see what are the differente scenarios I could have:
Make a Combat Challenge Attack (CCA): only on marked enemies, provoked by shifting (not moving) or making an attack that doesn´t include me, only one per turn, basic melee attack, doesn´t stop enemy from moving, nor does it benefit from AoO related feats or features.
AoO: provoked moving (not shifting) or making a ranged/area attack. Only one per turn, and can benefit from various feats and prevents enemy from moving.
Adyacent enemy (not marked)
Shifts - No
Moves - Provokes AoO
Attacks (non-ranged/area attack) you - No
Attacks (non-ranged/area attack) other - No
Makes ranged/area attack including you - Provokes AoO
Makes ranged/area attack NOT including you - Provokes AoO
Adyacent enemy (marked)
Shifts - Provokes CCA
Moves - Provokes AoO
Attacks (non-ranged/area attack) you - No
Attacks (non-ranged/area attack) other - Provokes CCA
Makes ranged/area attack including you - Provokes AoO
Makes ranged/area attack NOT including you - Provokes AoO and CCA
So, an enemy can still avoid my AoO, by shifting (and provoking a CCA which doesnt´prevent moving) and then doing something else.
This seems quite complex.
