Singed rework concept
One of the main points behind singed is that how killing him is necessary, but difficult and without reward.
P: Chemoinfusion When singed takes lethal damage, the chemicals rushing through his veins prevent a full death. As a result, killing singed grants neither gold nor experience, and his death timer is reduced by 25%.
W: Mega adhesive Singed is immune to displacement spells while he stands in Mega Adhesive.
R: Insanity Potion New: Now grants a shield equal to 30/35/40% of singed's maximum mana on cast.
