A Spell Combination is a order in which Spells are casted in order to receive a bonus.
The Enchantress has Eleven Spell Combinations.
Hot Flash! ? Only requires Enchantress; Spell Order is Ice Storm + Fire Storm =
Hot Flash! Group Combo. The Single Target Hot Flash! Spell Order is Frost Bite + Fire Storm = Hot Flash! Single Target Combo. Effects: Blasts target back temperately stunning them. Also casts 1-3/10ths damage extra of Fire Storm.
Nature Strike! ? Requires both a Enchantress and Bird; Spell Order is Thorn Wall + Lightning = Nature Strike! Group Combo. The Single Target Nature Strike! Spell Order is Thorn Root + Lightning = Nature Strike! Single Target Combo. Effects:Stuns target temperately and reduces Dodge. Also casts 1-5/10ths extra Lightning damage.
Terror! ? Requires both a Enchantress and Bear; Spell Order is Nightmare + Hell Scream = Terror! Group Combo. Effects: Debuff is 10-25% more effective.
Face Melt! ? Requirements: Keeper Staff of the Cosmos; This is more of a weapon bonus then a combo but it appears the same way combos do so I will post here. Face Melt! is additional fire damage casted from Keeper Staff, Its the weapons special ability. I notice it usually only happens if Keeper Staff is not attacking any other targets around the main target (Splash Damage).
Humiliate! ? Requirements: A barrel; If you blast a barrel while a enemy is near it. The enemy will take large amounts of fire damage, Loose all Buffs, blasted back and temperately stunned. Your character will automatically cast the Laugh emote.

The Single Target Shattering Blast Combo Spell Order is Frost Bite + Stomp = Shattering Blast! Single Target Combo. Effects: Blasts enemies back temperately stunning them. Casts 1-5/10ths extra damage of the Stomp attack.
Fearless! ? Requires only a Enchantress; Survive near death by casting Heal spell. Effects: Heal is slightly more effective; effects stack until death or level end.
