Arcane Echo

Description
If you cast a "spell" in the next 20 seconds, Arcane Echo is replaced with that spell for 20 seconds. Arcane Echo ends prematurely if you use a non-spell skill.

Comments
After casting Arcane Echo and then casting another spell, you get 20 seconds during which the spell cast is available to be cast from two skill slots, with separate timers for each. After this you must wait the full 30 seconds before using Arcane Echo again.
