Solmyr is a very potent hero depending on the size of the map. Access to chain lightning, a level 4th spell, speeds up early exploration and eases mid level fights. Specially in small and medium size maps this can give the needed advantage to achieve victory. At higher levels, his chain lightning may become as potent as implosion in terms of pure damage output over the first two targets. However, in large and extra large maps, sorcery is somewhat useless skill, because creature stacks can do much more damage and therefore better skills to sorcery slot are available.
