Balancing Spells

[wstsdwgrrr]

Alright I need help balancing some new spells I've added in, and I would appreciate any advice/comments:

Let me summarize real quick so this makes sense, there is a job system where each player can be a certain job (Final Fantasy Tactics/FFXI) based on certain requirements, and each job has its own specific 6 abilities/spells.

Monk Abilities/Spells -

Repeating Fist - 30mana - no cast delay - physical damage - must be beside the target - Hits a target 4 times with damage decreasing on every hit. Damage is equal to 16% of the player's wrestling skill, the 2nd hit does 50% the damage of the first, 3rd hit does 25%, and 4th does 12.5%

Dual Fist - 25mana - no cast delay - physical damage - must be beside the target - Hits a target twice simultaneously with damage equal to the 15% the player's wrestling skill on each hit

Chi Blast - 20mana - 1/2second cast delay - every element20% - Sends a fireball at the target, and does damage ranging from 15% to 30% of the player's wrestling skill. It does more damage the lower life the caster has.

Stigma Magic - 10mana - no cast delay - Cures the caster.

Chakra - 20mana - no cast delay - Recovers the caster stamina and hit points equal to 20% his wrestling skill, and mana equal to 3% his wrestling skill.

Secret Fist - 35mana - no cast delay - phyiscal damage - must be beside the target - Hits a target with damage equal to 25% the player's wrestling skill, but the damage is delayed 30 seconds, so the target does not take damage until 30 seconds later.

I've been having trouble balancing these...I'd appreciate feedback. Thanks.
