Stats & Training
Defense and Attack carry most of Aron's stat budget. Speed's the obvious dump stat. Common in the wild and yields 1 Defense EV. Follows a slow 1.25M XP grind.
A POKéMON that is clad in steel armor. A new suit of armor is made when it evolves. The old, discarded armor is salvaged as metal for making iron products.
Aron Weakness
Aron is weak to Fighting, Ground, and Water. Watch out for Fighting and Ground attacks, those deal 4x damage. On the flip side, it's immune to Poison-type moves entirely. With 9 resistances, the defensive profile is strong. Aron's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Fighting, Ground |
| 2x (Weak) | Water |
| 0.5x (Resist) | Ice, Psychic, Bug, Rock, Ghost, Dragon, Dark |
| 0.25x (Resist) | Normal, Flying |
| 0x (Immune) | Poison |
