Interesting new Demigod idea

Ok, so i was reading another forum where somone mentioned the idea of clonning your demigod. Obviously a complete clone is way overpowered if you have to kill both (or all) of them to destroy the DG and useless if they are one hit paper clones. Anyway, I started thinking about a "splitting" ability. Kind of like the panda in WC3. The backstory would be about a tragic hero who was torn between protecting his kingdom and seeking out his own ambitions, somehow he is immortalized in statue.

He would appear as a two sided statue (a face on both sides) a little taller than oak but a bit shorter than rook. One side would be procelain or lime stone or something vibrant white, while the other side would be Obsidian. His abilites would be based around this theme. (here are some ideas i had for them)

1. Split - Split into the two sides, one light and one dark statue, both with x% of remaining health (25% at level 1 40% at level 3 maybe?). While split both sides also have reduced mana (probably also an x%). Lasts maybe 40-100 seconds or so? (with a very sizeable cooldown AFTER the ability finishes). Only one side needs to be alive when the skill ends and the character will be recreated at the site of one of the two (if both are alive) sides, chosen randomly.

2. A shield that increases deffense by an integer value and gives a small chance to block all damage and absorb 5-20% of what damage would have been dealt. (can only be used by the light side when the DG is split) this can be cast on allies as well.

3. Curse type of skill. A debuf to movement and attack speed (5%?) as well as damage over time similar to (but less than) UC's poison spit. I was also thinking it might be cool if it did ALOT less damage but it prevented healing over time for the duration. This skill could only be used by the dark side during split.

4. passive skill that on death both sides have a final word. The light side will heal allies and the dark side will damage surounding enemies, not for too much damage but enough to be relevent and worth investing in. (only the repective effect occurs while split)

5. Bi-focus - each side acts on it's own ambitions and will attack seperate targets (the dark or light side will randomly choose surounding targets) but each side interfears with the other so they do reduced damaged, maybe 40% less at level 1 and so on?

6. A skill focused on the internal chaos of the DG, either does light or dark. Heals everything around it for a good amount, or damages everything around it fora  good amount respectively. While split both DGs can use this skill but for light it will only heal and for dark it will only damage. Also, the power could be reduced while split.

7. Routlet - a skill that targets either a friendly or enemy demi-god and does randomly healing or damage for a random amount based on a Poisson distribution (so it usually has an average value but also VERY RARELY can have huge values too).

8. Chaos Emrace (dark) - adds a randomly chosen amount of damage to your attacks but only while in the combined form.

9. Chaos Emrace (light) - adds a randomly chosen amount of life steal to your attacks while in the combined form.

So basicaly the idea is to work around the mechanic that it's really two DGs that are stuck together. It deals with the chaos between perfect good and perfect evil, there arn't many random values in other DGs skills so i thought it would be cool to have a character that can throw in some unpredictability, it also lets the player develop to the situation, you can be a hero killer or a good support. It's just a starting idea, i would love to have other people's input on this.
