Can you create an experience that adds a bonus to your attacks & Spellcasting attack bonus or only you can create experiences that modify skill rolls?
For example can you create an experience like this?
Abjuration Savant: You have a +2 bonus on any Spellcasting rolls to any spells that grants protection or Defense (i.e. Counterspell).
You can indeed use Experiences on Attacks or Spellcasting rolls. One of the Experience examples given is “Sharpshooter”, which you would struggle to find a use for outside of ranged weapon/spell attack rolls. Experiences are intended to be applied creatively, and GMs are encouraged to reward players for unconventional applications of Experiences. The Hope cost avoids scenarios of exploitation or imbalance between PCs.
Thank you!
