I finally beat Mechalag after a grueling, ten-minute-long battle (using my Tier 4 Chelon, Hastanno). Huge acheivement, it was a real struggle, but Hastanno pulled it off (with the help of his little KT ring!)

Congrats. I do find that shear sword+replica knocker is really good for a main attack since shear sword increases your pet's attack by 20 (for the battle) each use, which can be really helpful considering he takes a lot of turns to defeat (though it will still probably trim down on the number of turns quite a bit).

Congrats very much, he really is a pain when your pets are smaller tiers. But such an accomplishment to finally bring him down. Well done. C:
