TRAPS:
Put something like a freeze bomb. Its like a freeze spell but works on enemy troops. Duration similar. Can be upgraded.
Put something like spike. 1x1 similar to spring trap. Its like a one use trap. Bleeding damage for 4 secs min?
Something like quicksand 2x2 slows down enemy till they ctoss the tiles.


SPELLS:
How about something like a reflect spell that reflects damages done by defences while attacking. The damage is like done to the attacking defence for a certain amount of time. 1/4th damage lvl1 time 3 secs l. 2/4th damage lvl2 time 4secs. No other level cuz it can be difficult while defending.


TROOPS
Not much but you can add 1 or 2 more dark troops.

Lastly.. WALLS

Elixir upgrade or Lesser gold for all walls above lvl7 l. You choose.


Thank You.
