SMN energy siphon only available when high enough level for it.
Otherwise use energy drain. Between levels 40 and 51, summoner has energy drain but not siphon, but does have painflare. So siphon -> painflare does not make sense. It should instead be energy drain -> painflare
Also converts painflare to fester when painflare unavailable. Saves 2 buttons that are otherwise only needed in low level content. As this only affects hotbar configurations in low level level synced content it purely is a convenience and does not remove any skill from the game.
However this QOL feature is still useful to me. For example I like having an AOE and a single target hotbar, I switch between these with a controller button. being able to use energy siphon without having to rebind it every single time is helpful.
