After some deep thinking, he could only manage to think of two pros…
The first and the most obvious is the massive boost it provided in the stats, amounting to a total of 200.
This would be huge considering now that he has transformed into a monster, there might be a possibility that he won't be able to gain levels as he did when he was human or use the coins to upgrade his stats.
So in that sense, a boost of 200 stats would be massive.
The second and final would be the potential of this evolution path…
Think, when the reward Dhruv is getting in the third tier, is already this good, not exactly good but unique for sure. Then how much he could gain if he continued on this path...
Dhruv was well aware of this fact and would have chosen this evolution if it weren't for the wave that binds his hands and requires him to be at his strongest.
