Invocation drawbacks are flavorful debuffs that come with every invocation your warlock takes - the small price your warlock pays for brokering for power with outsiders like your patron.
These drawbacks are for roleplaying purposes only, and have no mechanical benefit or detriment to how your warlock functions. They are just for fun, and for you to expand how you roleplay your warlock's burgeoning madness and deformity.
- Aside from obsessing over strange things and occasionally turning uglier than usual, none.
- Some drawbacks may be somewhat more dramatic than others, but not to an unreasonable extent.
