Difficult profession advancement amplifies all attributes by 4 times.
For Doggy Two and others, they directly achieve a 5 times increase in nightmare mode.
After reaching level 81, Doggy Two's basic attributes become:
Strength: 9018, Agility: 3994.5, Physique: 2554.5, Spirit: 2554.5
Attack: 67635
Defense: 19155
Spirit Power: 37.5
...
With Dean McKenzie's [Skeleton Control] effect, the attributes increase to:
Strength: 10018, Agility: 4994.5, Physique: 3554.5, Spirit: 3554.5
Attack: 68135
Defense: 19655
Spirit Power: 37.5.
Yeah, it didn't increase by fifty percent because [Skeleton Control] is a standard third-turn skill, and its enhancement has a limit.
A single attribute increment of 1000 is already the upper limit.
However, even though Skeleton Control has a limit, [Bone Eruption] does not, as it is indeed an enhancement skill.
So, when Doggy Two triggers [Bone Eruption], attributes increase by 2.5 times, plus Doggy Two's own King of Bones with an 100% increase.
