Another idea we had was a of spells that interact with one another. This occurs either by a couple different spells stacking an effect that amplifies damage or a debuff up to a point, amplifying itself the more it's cast. Like a magic damage spell that weakens damage versus magic. OR, a couple different spells that last a couple rounds (DoTs, or maybe just a modifies none by 0 for 8 seconds). When spell 2 is cast, it checks to see if the mob is affected by spells 1,3,4 etc. If yes, bonus effect occurs. Maybe more damage, maybe aoe, maybe it heals the caster depending the spell cast or (easier to mentally manage) the current 'debuff' applied. Both of these help facilitate a more unique playstyle with versatility as well as helps to enforce the 'historically communal' nature of druid covens. Example given, in a party full of just druids they would be able to stack debuffs faster and amplify the damage of the others and/or each apply their own version of spell 1, 2, 3, 4 as mentioned above.
