Contracted Desire
Rank: D
Type: Ice, supportive
Duration: 4 posts
Cooldown: 7 posts
Description:
Out of a search for balance, Kateri has come to the realization that her attacks do little to help her allies. Her knowledge is nothing but causing her to gain power while causing her friends to be harmed in the process. Out of her desire to achieve balance, the demon Kazimir has permitted her to tap into his power for a period of time. This is achieved by channeling Kateri's desire to aid her friends through her life force, and magic power and emanating that will to the area around her. This will then manifests itself in a formation that encases the entire room with ice. This ice, rather than cripple her opponent and allies, encourages her allies to strive for better accomplishments in battle.
At Kateri's expense...
Allied Gains:
+30% Damage
+15% Speed
+10% Defence
+5% Reaction Time

Kateri Gains:
+15% Damage
+10% Speed
+5% Defence
-5% HP
-10% MP (regardless of rank)

Created Room looks like this without the beds:

Strengths:
1 Very powerful buff for team members
2 Allows for Kateri to be a true asset
3 Increases Kateri's damage output

Weaknesses:
1 Costs HP as well as increased MP that doesn't reduce with rank
2 Reduces Kateri's Damage Threshold
3 Reduces Kateri's Speed
4 Damage increase isn't nearly as powerful for Kateri as it is for her allies.

Needs clarifications on those weaknesses
