Guild Wars 2

does anyone know how the following things work in gw2
Crit multiplyer formula?
for exmaple my wep says 111dmg but crits for 560.
how does it work consider crit dmg/crit chance

what the cap(soft/hard) for Crit chance/crit dmg/power(attack)/defense/toguness

how does dmg skill effect only player consider the type of gear he got
how does it migrated by his armor+toguness

how does boons effect the defense and power of player and crit chance
Does for exmaple fury that give 20% chance effect crit chance by 20% chance or less if the player already got softcap or hardcap .

A critical hit (also known as a critical strike, or abbreviated to crit) is a type of hit that deals more damage (minimum 150% base + critical damage) than a regular hit.

The amount of additional precision required to increase the chance of a critical hit by 1% is determined by the following formula:

(0.0024 × Level2) + (0.06 × Level) + 1
