Anti-Form

If the holder of this feat is reduced to under 1/5 of their total HP, they can use their bonus action to transform into the "Anti-Form". This form shifts the user into a mere shadow of themselves, regaining all of their HP and temporarily boosting their AC and all attack rolls by +1. This form lasts for three turns, and then they revert back into their usual selves.

However, whilst in this form, the user cannot use any magic whatsoever or be healed by fellow party members, and all attacks must be melee attacks.

• If you're playing a rogue, sneak attack damage is disabled.
• If you're playing a barbarian, you are either no longer able to rage or are no longer raging.
• Druids are unable to Wild Shape while in this form, and this feat cannot be used if the druid is already in a wild shape.
• Second Wind and Action Surge are disabled for fighters who are in the Anti-Form.
• Clerics will be ignored by their deity whilst in Anti-Form, so they are unable to call on Divine Intervention.
• Bards can no longer inspire their teammates whilst in this form.
• Warlocks can no longer use their Pact Boons whilst in this form.
• Monks can no longer expend Ki Points whilst in this form.
• Paladins cannot utilize a spell slot to use Smite whilst in this form.
• The Ranger's Favored Enemy is ignored whilst in this form.
• Sorcerers and Wizards have minimal abilities when all of their spells are removed, so there is no additional downside.
