Beetle Endurance is a buff granted to the player wearing a full set of Beetle armor with the Shell equipped. The player only has to avoid being hit for a few seconds for the buff to start building up, one beetle each level. It takes about 3 seconds of not getting hit to gain an extra beetle. Each beetle adds 15% damage reduction, going up to 45%. If the player is hit at any moment, the total damage of the hit will be reduced by that amount and one beetle will disappear, reducing the buff by one tier.
