Use the Club of Trials until the latent effect disappears.
How to remove the latent effect:
You must perform Weapon Skills and Skillchains on monsters that con Easy Prey or higher.
You receive 1 point for opening/soloing a weaponskill, 2 points for closing a Lv.1 Skillchain, 3 points for closing a Lv.2 Skillchain and 5 points for closing a level 3 Skillchain.
You must accumulate 300 total points.
Once the elemental resistances disappear in the equipment menu, you are done. (You may also unequip and re-equip the Club of Trials to see if the bonus stats apply.)
Once in Ro'Maeve go to M-8 and click the ??? to spawn the NM named Eldhrimnir (best camp is at far south end in M-10, just a few mobs to kill for clear path to ???).
