Spell Blademaster

You may choose an element. Until the start of your next turn, you are considered to have mastered that element.

You unsheathe a melee weapon and enchant that weapon with an element you've mastered. Your weapon now deals the chosen element’s damage instead of its normal damage.

If you are not holding the enchanted weapon at the start of your turn, your weapon loses this benefit.

The weapon gains a +1 Power bonus to attacks until the end of the encounter.

You may make a Light Attack against all enemies within range. On damage, your attack applies an additional effect based on one of your attack's damage type. (If you are able to have multiple damage types on the attack such as through Holy weapon, you may pick any of the effects).

Arcane: The target loses 1 mana.
Fire: The target becomes Burning X, where X equals your Power x 3.
Water: The target becomes Soaked X, where X equals your power/2 (rounded down), until they take Lightning damage.
Lightning: The target is afflicted with Static X, where X equals your Power x 3. 
Earth/Frost: The target becomes Slowed until the start of your next turn.
Wind: You may push the target back 10ft.
Holy: You gain temporary hit points equal to your Power+5.
Dark: The target becomes Blinded 5 until after their next attack.

Your next Elemental Strike or Elemental Sweep ability used this turn may add in the effect of another element. This element must be one you have mastered and different from the effect that's already dealt by the attack.
