Laima statue reduces the cooldown of skills by 20%, if you hover over to the details of your skills the value of their cooldown changes.
However the value that’s being displayed in the tooltip is wrong
Example:
Heal without laima has 22 seconds cooldown, if we reduce it by 20% the cooldown should be 17s
Casting laima however, shows that the cooldown is reduced down to 13s which is false, however the cooldown of the skill is correct.
This may cause confusion to some players as to why their skill cooldowns take longer than what is shown in the tooltip.

Without Laima (Normal)
With Laima (cooldown should be 21)
