Hey, lol.
Another skill tree I thought of.
Elemental.
This ability lets the Doppelganger clone an Elemental of the target god. The elemental has 1/4 or 1/2 or 1/3 health of the targeted god (base health) each health level corresponding to to the level of the Doppelganger. The elemental can only do an auto attack and looks exactly the same as the god that is copied, except he is slightly transperant(see through). Elementals have no abilities and are used the same as a minions.
The elemental is the same as a minion. Doppelganger can have up to 2 elementals at a time at TOP level. so level 5 he can summon 1 elemental (with 1/4 hp and damage of targeted dg). level 10 he can upgrade health and damage of elemental to 1/3. , level 15 he can summon up to 2 elementals- but only one at a time, and level 20 he upgrades health and damage of elementals to 1/2 of the copied (or shadowed) god.
Also, doppelganger can summon up to 1, 2, and 4 of cloned minions. For example, he clones sedna, summons 2 Yetis. Then clones QOT upon cooldown, and summons 2 shamblers. If he clones a high level general and hits their summon minion ability, then he will only get 1 minion of that level at a time.
Also, if the targeted god has not chosen a minion build, then he won't be able to summon any minions.... but as rook he could put up a few towers, then clone LE and bat swarm the hell outta there.(IF LE is nearby that is.)
He is a "general" but cannot have idols. Why? Because potentially on maxing Clone ability and Elemental ability, he could have 2 elemental DG's with 1/2 health and 1/2 damage, plus 4 summoned minions IF he plays his cards right.
All minions would live until killed, no matter weather doppelganger is in shadow form, clone form, or switching to a new clone form.If max minions and elementals have been summoned, then no more can be.
So potentially you could have a clone of UB, with 4 nightwalkers plus an elemental of Rook and an elemental of TB, both with 1/2 dg auto attack and health attributes. That's about as good as a general with all idols and minion build IMHO.
Elementals health and auto attack damage % is respective to the BASE health of the targeted demigod.
