Wizard - Order of Diabolists
The Order of Diabolists is for wizards who find the hells seductive and irresistible, but who pursue their studies in a more restrained and orderly fashion than a head-first pact-forging warlock would.
The Order of Diabolists is effective as a jack-of-all-trades wizard, but leans into some of the summoning spells that are a little riskier and less used, normally. Forbidden Knowledge is a fairly straightforward ribbon, with the unusual perk of reducing the gold cost of your preferred summon spells. Hellfire Magic is the significant level 2 feature; a few times a day, you can change a spell or summon's damage to hellfire, with a significant damage boost (but hitting two resistances, potentially, so situational to use). Devil Summoner buffs up your summons and makes it harder to lose control — a very significant risk at all times. Sulfurous Tongue supplies a utility feature and also a boost to negotiations with powerful devils, a situation you're increasingly likely to find yourself in. And Tainted Soul is the ultimate result of your dark researches, allowing you to modify your own essence with fiendish traits (all defensive ones, basically).
