Archer's towers are very sturdy and are not easy to destroy as an attacker but don't delude yourself that you are safe.
At Level 5 Walls and below, towers can be blown away by:
- Archers on about a 3:1 ratio (eg 9,000 Archers will make mincemeat of 3,000 Towers), provided
the attackers Archery research is similar or higher than the defenders although this ratio changes to 5:1 if the defenders walls are level 6 or higher.
- Ballista - they stand-off and reduce Towers at little to no loss to themselves, also depending on Archery levels.
- Catapult - they stand-off and reduce Towers at little to no loss to themselves, also depending on Archery levels.
However when walls get to L6 and above the defenders chances dramatically increase as each level extends the Archer Towers range by 5%.
-with walls above level six the generally accepted ratio of archers to archer towers is 10:1, to avoid heavy losses.
