@tatsurou: rage increases the rate at which your skills cool down, this means that at max rage you could use your skills every couple of turns. A barbarian with an axe and strife attack seems to be the best option for crowd control
@Saruleon: telepathy lets you know where the monsters are located on the map so you can plan your moves around it and avoid getting into dangerous situations. Keen hearing is the same as telepathy but has shorter range
