I couldn’t really find anything with clear instructions on how one could easily make a skill which could only target another ally aside from the user. Is there any easy way to do this or does it require a plugin, and if so how is that done?
Typically, RM’s system will apply a skill’s effect to one target, all targets, or randomly. If you need something more complex, you’ll need a plugin.
If you’re using MZ, VisuStella-BattleCore* is your answer. It offers versatile functionality with a single plugin, such as targeting all except the user, or preventing the skill from targeting the user.
*CoreEngine required.
