Update of the day:
Enemies attack more often and more deadly.
Player now has shield (passive function).
Is the rolled shield value above the opponent's rolled attack value
the difference is deducted from the shield, the player does not suffer any damage.
The shield recovers automatically after about 5 seconds.
If the shield is consumed or the opponent's attack value is above the rolled shield value, life energy is deducted from the player.

Life energy and shield value can reach higher values through the player's higher levels.

Bugfixes:
Fixed a bug in combat logic.
