Kingdom Tower

Provide defense for the Kingdom land.
They have the same range as other towers.
They always have attack and defense stats similar to a fully upgraded Guard Tower (towers reduce dodge by 25%).
All levels of Kingdom Towers have repair costs as if they were level 1. Upgrading makes the cost per repaired HP cheaper.
Kingdom Towers can be upgraded from level 1 to level 5. Each level has more HP and adds to the Kingdom Influence score.
- Level 1: 2000 Bricks, 200 Crystal --> 10k HP (from Kingdom Flag)
- Level 2: 6000 Bricks, 600 Crystal --> 20k HP
- Level 3: 20000 Bricks, 2000 Crystal --> 30k HP
- Level 4: 60000 Bricks, 6000 Crystal --> 40k HP
- Level 5: 200000 Bricks, 20000 Crystal --> 50k HP
