Path of the Raging Mind

All Barbarians gain strength from their rage but why can't that strength be mental as well as physical.

Brainstorm

3rd-level Path of the Raging Mind feature

When you enter your rage, the wrathful power that grips your mind manifest itself as a psychic aura capable of mimicking the effects of certain spells. Anti-magic properties do not affect the aura. Apon entering a rage, you choose one of the following spells to mimic:  Arms of Hadar, Phantasmal Force, Hypnotic Pattern, Confusion & Hallow. The aura uses the spells radius, is always centered on you & uses INT for calculating spell/psychic MOD. The aura always behaves as if the spell was cast as a level = your PB - 1, with spells whose level exceed this threshold being unable to be selected. If the mimicked spell has no upcast feature, then it's DC increases by 1 for every level upcast. The aura last as long as the rage last but should the rage last longer than the spell duration then all saves against the aura's effect are made at advantage & all damage from the aura is halved. All damage done by this aura is Psychic. If the mimicked spell is concentration, loosing concentration fill cause you to drop your rage.
