Lightning Rod
Redirects single-target Electric moves to this Pokémon where possible. Absorbs Electric moves, raising Special Attack one stage.
Full effect
All other Pokémon's single-target Electric-type moves are redirected to this Pokémon if it is an eligible target. Other Pokémon's Electric moves raise this Pokémon's Special Attack one stage, negating any other effect on it, and cannot miss it. If the move's intended target also has this ability, the move is not redirected. When multiple Pokémon with this ability are possible targets for redirection, the move is redirected to the one with the highest Speed stat, or, in the case of a tie, to a random tied Pokémon. Follow Me takes precedence over this ability. If the Pokémon is a Ground-type and thus immune to Electric moves, its immunity prevents the Special Attack boost.
In game description
The Pokémon draws in all Electric-type moves. Instead of taking damage from them, its Sp. Atk stat is boosted.

Using Lightning Rod in Cobblemon
Abilities are passive and always active, so Lightning Rod costs you nothing to run. If it is marked hidden on a species above, expect it to be harder to obtain: servers differ in whether hidden abilities come from breeding, an Ability Patch, or events.
See the Pokedex for which abilities each species can have, and IVs, EVs and breeding for how to actually pass one down.
