OK, so it looks like we have Alembregh,Elspeth,Turlough,Terrick,Mohgyrm and Rament. That's a manageable party, with Duranom as (an NPC) Tank, sparing Elspeth the job.
XP:58,500 each
Levelled Items
Your item counts as whateer + it is currently at. Raising it in bonus points costs the following XP and requires the following Level minimum.
Bonus...XP Total........Level Min
+1...............200...............3rd
+2...............800...............5th
+3..............1400...............7th
+4..............2200...............9th
+5..............3500..............11th
+6..............6000..............12th
+7..............9300..............13th
+8.............12000.............14th
+9.............18000..............15th
+10............25000.............16th
At first glance, the totals spent might seem high.
Comparing this chart to the Oriental Adventures one shows a total of 25,000XP spent to bring your item to +10 equiv (+5 in bonus max, as per DMG +special abilities), while OA has you at 30,880.
As well, I lowered the level requirements of the Character by quite a bit. Two levels in the end.
Stats on the found items in a little bit, need to get out the Notebook with them (parents are visiting right now, I'll be hanging out with them for the next few hours).
