When Brewmaster drops below 50% Health he gains a Status Resistance buff and his movement speed alternates every 1 second between being faster and being slower. The effect becomes stronger at lower health, scaling from 0 up to max values at 20% Health. Max Status Resistance is 10.5% + 0.5% per Brewmaster's level up, Max Speed Increase is 25%, Max Speed Slow is 10%
