Critical Hit

All weapons and most spells have a chance of getting a critical hit. For weapons and many spells, this means doing higher damage. However, a wide variety of critical hit effects exist, so check the spell to be sure what it does.

Calculation
Note: ''All weapons have a "Critical Hit Bonus", listed in the same panel as crit rate, range and AP cost. This does not affect crit rate but defines how much extra damage a critical hit does. Put simply, this bonus is what makes critical hits actually critical.''

Crit rates are on the form 1/x. Equipment and skill bonuses to crits reduce x by their bonus. Thus a 1/50 crit rate becomes 1/40 with +10 crit.

Agility also increases crit rate, but the specific formula is not known. The following results come from a post by lichen on the offical forum. "Base crit" is the x value after equipment and skill modifiers, so agility can only roughly double your crit rate.

Base crit : 5 10 15 20 25 30 35 40 45 50 Agi =  0 : 5 10 15 20 25 30 35 40 45 50 Agi = 10 : 4  9 14 19 24 29 33 38 43 48 Agi = 20 : 4  8 12 17 21 25 30 34 38 43 Agi = 30 : 3  7 11 15 19 23 27 31 35 39 Agi = 40 : 3  7 11 15 18 22 26 30 34 37 Agi = 50 : 3  7 10 14 18 21 25 28 32 36 Agi = 60 : 3  6 10 13 17 20 24 27 31 34 Agi = 70 : 3  6 10 13 16 20 23 27 30 33 Agi = 80 : 3  6  9 13 16 19 23 26 29 33 Agi = 90 : 3  6  9 12 16 19 22 25 29 32 Agi = 100 : 3 6  9 12 15 19 22 25 28 31 Agi = 110 : 3 6  9 12 15 18 21 24 28 31 Agi = 120 : 3 6  9 12 15 18 21 24 27 30 Agi = 130 : 3 6  9 12 15 18 21 24 27 30 Agi = 140 : 2 5  8 11 14 17 20 23 26 29 Agi = 150 : 2 5  8 11 14 17 20 23 26 29 Agi = 160 : 2 5  8 11 14 17 20 23 26 29 Agi = 170 : 2 5  8 11 14 17 20 22 25 28 Agi = 180 : 2 5  8 11 14 17 19 22 25 28 Agi = 190 : 2 5  8 11 14 16 19 22 25 28 Agi = 200 : 2 5  8 11 13 16 19 22 25 27 Agi = 210 : 2 5  8 11 13 16 19 22 24 27 Agi = 220 : 2 5  8 10 13 16 19 21 24 27 Agi = 230 : 2 5  8 10 13 16 19 21 24 27 Agi = 240 : 2 5  8 10 13 16 18 21 24 27 Agi = 250 : 2 5  8 10 13 16 18 21 24 26 Agi = 260 : 2 5  8 10 13 16 18 21 24 26 Agi = 270 : 2 5  7 10 13 15 18 21 23 26 Agi = 280 : 2 5  7 10 13 15 18 21 23 26 Agi = 290 : 2 5  7 10 13 15 18 20 23 26 Agi = 300 : 2 5  7 10 13 15 18 20 23 26 Agi = 310 : 2 5  7 10 12 15 18 20 23 25 Agi = 320 : 2 5  7 10 12 15 18 20 23 25 Agi = 330 : 2 5  7 10 12 15 17 20 23 25 Agi = 340 : 2 5  7 10 12 15 17 20 22 25 Agi = 350 : 2 5  7 10 12 15 17 20 22 25 Agi = 360 : 2 5  7 10 12 15 17 20 22 25 Agi = 370 : 2 5  7 10 12 15 17 20 22 25 Agi = 380 : 2 5  7 10 12 15 17 20 22 25 Agi = 390 : 2 4  7  9 12 14 17 19 22 24 Agi = 400 : 2 4  7  9 12 14 17 19 22 24

Also note that it is impossible to reach a better critical rate than 1/2.
