As far as ice comet is concerned ... i put all 5 training points
into research every level since 16 keeping it maxed and succedded on the
1st 9/9 attempts of lvl 49 spells, the runes of BOTH frost and astral
can be found on the Dino in oot im 100% sure, but i do believe that any
49+ MoB has a chance of dropping lvl 49+ runes, words etc...(plus the
dino drops diamonds/blk sapphires/jacinth, as do all 50+ mobs)

Kronon: 2 words for where to get experience at higher lvls without
killing guards ... Seafury Cyclopses ... these guys are so plentiful
that their isle can support at least 5 groups comfortably with each
group pulling nonstop one after the next, all of these one-eyes are lvl
39-42 or so making them good exp all the way up to 50 ... they hit about
the same as regular cyclopses, the only difference being that they hve
about 5000 hp's... their isle is located at about 1900, -6600 (next to
the isle that spawns the aincent cyclops)...However, be warned: also on
this isle is a lvl 45 cyclops named Quag Maelstrom, HE hits like a
mother and has LOTS of hp's, not to mention a nasty mana sink spell that
will drain you to oom very fast if he lays his mitts on you, that being
said he can easily be taken down by a competent group 45+ (he can be
killed by a group of 40+, but they better know what they are doing) ...
killing him however is terribly inefficient and not worth the time spent
per exp gained...he drops nothing of note and will respawn quickly, so
its not like if u kill him you puller wont have to deal with him again
soon.
