>>44287255doing some armchair math here at 4* level 105 and with 2/3 affinity 10/20 gold tarts tech venomoth stats will be:
HP: 450
Att: 194
Def: 147
SpAtt: 194
SpDef: 147
Spe: 262
The stats will actually be a bit higher than this because the level cap will raise from 105 to 120 but I dont know the stat boosts for specific sync pairs on levelup.
