Needs a bit more detail and balancing, but I like the idea!
Need to add:
- What makes this unit/spell unique compared to the other units/spells in the game
- What kind of strategies this new unit would enable (concrete examples are best)
- What kind of army composition includes this unit or, how it could combine with other units for more advanced strategies
- How someone could redo their base to protect against attacks from this unit
- Appearance
- Favourite target
Seems like a valid idea, might need some balancing as clones of pekkas would be completely OP. Maybe something like, can't lock onto golems, lava hounds, dragons, or pekkas? That would balance it out a bit. Agree with AnthonyVince, clone time should then be 15 sec with the new restriction.
Great Idea Though!
