Hello everyone, I have been trying to figure out how to achieve something in Trinity using the databases. When you first create a character you spawn with a starter ability for example Cobra Shot. I would like to remove this ability and instead reward it when the player hits Level 3. How do I go about doing this? Or is it even possible? I managed to disable it when you start at first spawn by deleting the relevant record in "playercreateinfo_action" but as soon as I hit Level 2 the ability comes back. Any help would be greatly appreciated! Thanks in advance. Nathan.
