Usually I play PVM. It's not that i don't like PvP, i just haven't build any good character to it and there wasn't too many occassions. My favorite peerless is Twisted Weald and Bedlam, that's where I spend most of the time when i'm online. I like to hunt for new minors, ML artifacts, Doom artifacts. For more spice I like to visit Despise Champion spawn alone and gather powerscrolls.
My favorites template is Tamer-Bard, on the second place is champer (mage, necro and spellweaving) which is perfect for Despise Champion spawn. For fun I use my Archer with Bushido, Ressisting Spells for hunting Yamandon in Tokuno Islands
When it comes about scripting i meant RunUO script's and small scripts in Razor. For RunUO I wrote some bugfixes, extensions for my friend who is running free uo shard. Nothing special just few new creatures, enhanted faction items or events similar to that known from OSI.
