Cold drakes are three slots, spawn with (using norm not full ranges) 115-125 tactics, 105-115 wrestling, 610-660 str, and 480-500 hits. They have one innate ability dragons breath. They can learn myst, chiv, sw
After patch 3 slot white wyrms spawn with... less health, 350-450 strength (yet to see a super str ww spawn at 3) no good overlaps on skills. Their stats are much lower due to the "magery/eval penalty" as that costs 1500 training points. However they don't have any abilities other than their magery.
