Build Battler

Added Build Battler (up to a maximum of 200% longer placing!)
Added Rage Mode When a low combat level player is hit by a high combat level player, there is a small chance that Rage Mode will activate, giving them Speed III and damage boosts.
Changed the Strength I effect in Blood Bath to Strength Chaining (+30% per kill up to a maximum of +150% damage)
You can now only use Push comes to shove on yourself.
Push comes to shove punch levels have been reverted (Punch 1/5/7 instead of 1/2/4).

Patch notes from this stretch

Added Dirty (Resistance 2 for 4 seconds on kill)
Added Multi Kills Getting double/triple/etc kills gives your kill higher rewards, up to a maximum of 50% extra.
