Big Guy
Detona gains a stack of Big Guy for 12s each time it or Barats damages an enemy with their skills (up to 10 stacks). Each stack of Big Guy increases Detona's size and grants 4 - 10 (scales with the level of Detona's Welcome). At max stacks, Detona gains 20% extra Resilience, and its Basic Attacks are replaced with Trample, which deals (+140% Total Physical Attack) (+3.5% Max HP) Physical Damage to enemies in a circular area, slows them by 40% for 0.2s, and refreshes the duration of Big Guy with each hit.
