I'd like it if the costumes were usable throughout the year. It'd make for an incredibly useful tool for player events. I love this idea though!
(far fetched) Overlord CTF Event or Mega Monster CTF EventDress up in your favorite costume and "tame" monsters from the arena to aid in your team's epic CTF located on a huge open arena (think color wars back on OSI test server, north Minoc w/castles?). The monsters you "tame" can only be done so if you are wearing the same disguise and will have "X" difficulty to "tame". After a successful "tame" the monster will be aligned to your faction, de-spawn, and reappear somewhere in your base (castle or something custom?). Example slots: Skeletons - Zombies - 1 slot Liche - Daemon - 4 slots Dragon - Wyvern - 7 slots Halloween Boss - 8 slots *incredible low chance to "tame" The team that wins the CTF will earn a piece of a costume. - Random teams!! - Each side starts with X amount of mobs in their base (Good luck with the coding) tl;dr: Players dressed and named after monsters killing monsters that can actually be players while players dressed as monsters tame monsters for base defense.
