It stacks up whenever you normally make an attack, because each attack applies the buff. When you crit or bash, it does not apply the said buff and so stacking stops. Once you attack again when the target still has the buff though, it stacks again. So at level 2, if it stopped at, for example, 6, the next attack still deals 12 damage, then 20 damage at the preceding attack. It does not start all over again, unless the buff expired. |
