Tamalan Arena is a PVP event at 17:00. You buy skills for 5s each, 4 at the max, which can be upgraded to level 5 with Duel Badges (Start out with 30, more gained for being in Tamalan and/or killing someone) and the same verision of that skill (ex: 5 Fireballs for a level 5 fireball, including Duel Badge cost)

Will edit more later, Awe.
