How to fix it??
252+ Atk Choice Band Adaptability Tera Stellar Crawdaunt Crabhammer vs. 252 HP / 16+ Def Mew: 380-447 (94 - 110.6%) -- 62.5% chance to OHKOI'm not sure if this thread is the right place, but on Stellar Adaptability calcs the calculator uses 2.5x STAB which does not appear to be correct
Base calc (no STAB, 1x):
252+ Atk Choice Band Crawdaunt Earthquake vs. 0 HP / 0 Def Absol: 256-302 (94.4 - 111.4%) -- 68.8% chance to OHKO
Possible damage amounts: (256, 259, 262, 265, 268, 271, 274, 277, 280, 283, 286, 289, 292, 295, 298, 302)
Adaptability (2x):
252+ Atk Choice Band Adaptability Crawdaunt Crabhammer vs. 0 HP / 0 Def Absol: 512-604 (188.9 - 222.8%) -- guaranteed OHKO
Possible damage amounts: (512, 518, 524, 530, 536, 542, 548, 554, 560, 566, 572, 578, 584, 590, 596, 604)
Tera-Water Adaptability (2.25x):
252+ Atk Choice Band Adaptability Tera Water Crawdaunt Crabhammer vs. 0 HP / 0 Def Absol: 576-679 (212.5 - 250.5%) -- guaranteed OHKO
Possible damage amounts: (576, 583, 589, 596, 603, 610, 616, 623, 630, 637, 643, 650, 657, 664, 670, 679)
Tera-Stellar Adaptability (2.5x? Seems wrong):
252+ Atk Choice Band Adaptability Tera Stellar Crawdaunt Crabhammer vs. 0 HP / 0 Def Absol: 640-755 (236.1 - 278.5%) -- guaranteed OHKO
Possible damage amounts: (640, 647, 655, 662, 670, 677, 685, 692, 700, 707, 715, 722, 730, 737, 745, 755)
252+ Atk Choice Band Adaptability Tera Stellar Crawdaunt Crabhammer vs. 252 HP / 16+ Def Mew: 380-447 (94 - 110.6%) -- 62.5% chance to OHKO
252+ Atk Choice Band Adaptability Tera Water Crawdaunt Crabhammer vs. 252 HP / 16+ Def Mew: 342-403 (84.6 - 99.7%) -- guaranteed 2HKO
In my testing, I found that the damage of Stellar Crabhammer is actually less than both of these. The damage was around 80. The actual range seems to be similar to stellar without adaptability, which would be:
252+ Atk Choice Band Tera Stellar Crawdaunt Crabhammer vs. 252 HP / 16+ Def Mew: 304-358 (75.2 - 88.6%) -- guaranteed 2HKO
But the make interesting part was turn 2, when the range fell below this again. Doing around 60. So the range would be similar to this.
252+ Atk Choice Band Crawdaunt Crabhammer vs. 252 HP / 16+ Def Mew: 228-268 (56.4 - 66.3%) -- guaranteed 2HKO
My conclusion is that Tera Stellar basically changes your type so you don't get Adaptability boost on Crabhammer anymore. So, the calc is very wrong.
