A unit that a hero summons shouldn't really take the place of another hero, especially when this type of hero has a huge strategic difference to most other characters Quote bebaxt
I read all of his suggestion and it sounded to me just a copy of Worker's Titan. It has a huge HP, regenerative ability. And you cant make him faster with ms auras just as Wosfreak suggested '' slow, huge, survivable(even without support), not very good at dealing damage''. It will probably live much longer than a copy hero whose hp would hardly reach to 100000 with best items in game unless Wosfreak specifies what he has in mind.
Main ideas for the kit I think would be % missing health regen (the lower it's health is, the more regen it gets) and stats that scale up based on the duration of the game (Because since it's taking the place of an important objective, it's going to need high bases to survive with likely less gold income in games with more players.)
It would take root in an area to access most of it's combat functions, with mechanics that reward setting itself up in a spot, like spawning roots over time that attack enemies (Like that Tentacle summon).
Armor Type might be weird. Maybe it should just have Fortified Armor all the time; it's not the best armor type, so maybe there should be some way to improve it (durability should be it's strong suit).
Although the concept is sounding more and more like a PvP hero, It'd be cool to see something like this in the normal game-mode. I don't know if the character would end up being team-comp situational or overpowered, but it's a neat concept.
Unless he was given some kind of immunity to one-shots or %health damage, I wouldn't imagine the character being useful against the super-endgame bosses.
Can't give any specifics right now, but if the idea has merit I'll definitely polish up a complete kit (no numbers though)
