I'm relatively new to TTRPGs and completely new to making Wizard characters. I'm currently trying to make a Wizard, and having trouble fully understanding the Grim Tendrils spell from the Pathfinder Playtest (2nd edition):
Black shadows curl out from your fingertips and race through the air, taking the form of ephemeral comes spiked with thorns.
You deal 2d4 negative damage and 1 persistent bleed damage to living creatures in the line, depending on their fortitude saves.
Negative damage would mean healing them right? But that seems weird since it has thorns. Looking in both the Pathfinder books in the playtest as well as online I don't see any explanation for this. Is it just me or is it really unclear?
What is negative damage?
