There are a fixed set of bonuses that can be found on items, having varying effects on the outcome of battles. Sometimes it can be difficult to assess which items are the best due to the confusing nature of the bonuses. In particular, many bonuses are really percentage (%) bonuses, even though the percent sign is not present. Another source of confusion is that not all bonuses occur for every race; in particular, the bonuses for T9 units are different for each race. Finally, some bonuses can appear twice on the same item, doubling the theoretical maximum bonus. The vast majority of bonuses can appear on any item, except for Magic bonuses, which can appear only on Magic items (ie secondary items, equipped on second equipment screen). Finally, there are some bonuses that you might assume exist due to symmetry reasons, for example +melee ATK %. Since +ranged ATK % is quite common, you might assume the melee version exists as well, but it does not. These bonuses have been listed below with a note that they don't exist, to avoid questions asking why they are missing from the list.

Combat Equipment Bonuses[edit  edit source]
InGame Description  Bonus Effect Explanation 

Increases Hero's maximum unit allocation : X  Increases the maximum number of units your hero can carry by X%. X ranges between 1 and 10. Can occur twice on the same item. It modifies the following equation to determine a hero's total force:
TotalForce = BaseForce x (1 + MaxUnits/100 + GuildBuildingLvl/100) + ArenaRank Bonus This modifies your base unit allocation as determined by hero level, and it is additive with the Guild Building bonus. 
Increases Hero ATK : X  Increases your hero's base ATK attribute by +X. X ranges from 1 to 10 
Increases Hero DEF : X  Increases your hero's base DEF attribute by +X. X ranges from 1 to 10 
Increases Hero SPD : X  Increases your hero's base SPD attribute by +X. X ranges from 1 to 10 
UNIT's HP increases: X
Increases UNIT's HP: X 

UNIT's HP increases %: X
Increases UNIT's HP %: X 

UNIT's ATK increases: X  The unit identified by UNIT will have it's unit attack increased by the fixed value +X.
This property is known to exist for T1 through T6 units, and does not exist for T9 or T10 units. X ranges between 1 and 5 (unknown if actual max). 
Increases UNIT's ATK % : X
UNIT's ATK Increases % : X 
The unit identified by UNIT will have it's unit attack increased by +X% (percent).
It is believed, but unconfirmed, that fixed bonuses are applied first (and thus benefit further from % increases). This property is known to exist for T7, T8 and T10 units, Bone Dragons and Green Dragons. It is known to not exist for Angels and Monsters. T7 units: X ranges between 3 and 6 T8 units: X ranges between 3 and 6 T10 units: X ranges between 3 and 6 Bone Dragons: X ranges between 12 and 22 (unknown if this is actual max). < translation error, should be DEF Green Dragons: X ranges between 3 and 7. This bonus is very rare. 
UNIT's DEF increases: X  Usually, X is a value between 1 and 25, in which case the unit identified by UNIT will have it's unit attack increased by the fixed value +X.
This property is known to exist for T1 through T6 units and Monsters (orc T9), and does not exist for T10. Alternately, X can be a value between 0.16 and 0.22, in which case it is presumably affecting the internal damage calculation more directly. < translation error should be SPD, only appears for Harpy like Bone Dragon's massive ATK bonus However, current damage formulas do not have an obvious place where these values make sense in the context of Unit DEF. 
UNIT's DEF increases % : X
Increases UNIT's DEF % : X 

UNIT's SPD increases : X  Sometimes X is a number between 1 and 10, in which case X presumably is a percentage increase of the unit's base speed.
How this is different from the speed bonus explicitly labeled as a percentage is unknown. Other times, X is a number between 0.1 and 0.5, in which case X is a fixed value. Definitely does not affect map travel speed. Unknownwhether this is intentional, could be an extension of the Fountain of Pegasus, etc. glitch. 
UNIT's SPD increases % : X  
UNIT's load increased by %: X  
Increases the probability of halfdamage to UNIT: X  
Increases the probability of doubledamage to UNIT: X  
Increases load of returning soldiers: X  
Increases melee unit HP : X  
Increases ranged unit HP: X  
Increases melee unit ATK: X  
Increases melee unit DEF : X  
Increases range unit ATK % : X  
Increases range unit DEF % : X  
Increases melee unit SPD: X  Increases the base SPD of a melee unit on a percentage value. Adds up. Final speed = 'Unit SPD * (1+X/100) + '(HSPD 10) * 0.02 
Increases range unit SPD: X  Increases the base SPD of a ranged unit on a percentage value. Adds up. (see above for the formula) 
Increases range unit load %: X  
Increases damage caused by melee units: X  
Increases damage caused by ranged units: X  
Reduces damage received by melee units: X  Lowers Base Damage on melee units by X% 
Reduces damage received by ranged units: X  Lowers Base Damage on ranged units by X% 
Increases probability of doubledamage to melee units: X  
Increases probability of doubledamage to ranged units: X  
Increases probability of halfdamage to melee units: X  
Increases probability of halfdamage to ranged units: X  
Increases the chance for melee units to act twice : X  Increases the chance for melee units to take another action after their previous action by X%. X ranges between 1 and 5.
Note that this is not a chance to act twice, but a chance to act again. There is no limit to the number of consecutive actions one unit can take. Therefore, the actual amortized damage dealt by this ability is compounded. Damage bonus = SUM(i = 1, INF) { (X/100) ^ i } (obviously, you need to calculate the limit as the upper bound goes to infinity) As a result, an aggregate 50% chance to act twice would on average always yield one extra turn, however the theoretical max is 43%. Note that the chance to act twice is in all cases better than a chance for double damage with equal values for X, and as X increases becomes ever better. For aggregate values of X: 5: Equals 5.26 Double Damage 10: Equals 11.11 Double Damage 20: Equals 25 Double Damage 30: Equals 42.86 Double Damage 40: Equals 66.67 Double Damage 43: (Theoretical maximum) Equals 75.44 Double Damage When you factor in the chance of double damage wasting damage through overkill on one stack, acting twice becomes even more valuable. The theoretical maximum is a combination of 8 items giving +5 each, and a a racial skill giving +3, for a total of 43%. (actually 44% due to 1% from first mate's hat (ocean treasure item)) 
Increases the chance for ranged units to act twice: X  See the discussion for chance for melee units to act twice for details.
