Playing PF1e for the first time this year, been having a blast with a heavens shaman that's focused on summoning this huge frog deity which is just a Giant frog with a spiritual guardian template slapped on it, supported by some homebrewed support relevant to my PC (channel energy) and now with a mythic level, an Agile Template via mighty summons.
However, For my first feat, I just picked whatever seemed like a safe option. I inquired the DM about it, and he's letting me retrain it into whatever else I qualify for at level 7. Pic related.
In combat, I mostly summon the Frog and debuff enemies, alongside bringing some buffs and divine-caster-themed solutions from a distance.
With that in mind, what feats should I consider instead of combat casting? I keep scrolling through the humongous feat list and honestly I get a bit overwhelmed.
