Alright. It seems Whelplings at level 1 give the following (best stats are starred)
Azure:
155 HP
12 Power
10 Speed
Crimson:
145 HP
13 Power*
12 Speed*
Dark:
155 HP
13 Power*
10 Speed
Emerald:
161 HP*
10 Power
11 Speed
So if that's at level 1, I have a few which I have leveled to 10.
Level 10
Azure:
652 HP (+55.22 per level)
123 Power (+12.33 per level)
104 Speed (+10.44 per level)
Crimson:
555 HP (+45.55 per level)
129 Power (+12.88 per level)
116 Speed (+11.55 per level)
Dark:
652 HP (+55.22 per level)
129 Power (+12.88 per level)
96 Speed (+9.55 per level)
So that leaves me with this.
Guess for 25:
Azure:
1480 HP
307 Power
260 Speed
Crimson:
1238 HP
322 Power
289 Speed
Dark:
1480 HP
322 Power
239 Speed
So despite not having my Emerald Whelpling leveled up yet, I can look at the base stats and take a guess how things may go.
Azure: Bruiser. Burst damage with CC.
Crimson: Glass cannon Nuker. Extreme damage with survivability option (removes a good portion of damage each turn.)
Dark: Anti-support Bruiser. Special move that reduces healing for multiple turns.
Emerald: Support. Heals your team and stays alive with a large health pool.
AWESOME. I love it!
I'll keep this thread updated.
