This is a WIP document. It will be updated as more information is discovered.
The evasion calculator is here.
Introduction
Besides critical hits, there are four non-standard damage values that exist:
- Deflect/Graze (Grey Number)
- Dodge
- Miss
- Immune
The first two are related to the attacker's offense stat in relation to the defending unit's defense and dodge respectively. Offense can be thought of as an attack's accuracy.
Offense is reduced by 20 when suppressed.
The last two are related to damage reduction.
Deflect
Deflects tend to result in the attack dealing 10% of its base damage, though there are exceptions.
Exceptions (WIP):
- Saboteur C4 (50%)
- Gun Truck
- Wolf Cruel Bus
These seem to deal 20-50% of base damage.
The odds for an attack to deflect is given by this formula:
\[\text{Deflect chance (\%)} = \text{Defense} - \text{Offense} + 5\]
For example:
- The Ancient Construct has a defense of 40.
- A R5 tank killer has 40 offense, and 20 while suppressed.
The damage reduced on average is calculated as follows:
\[\text{Total Damage Reduction from Deflects} = (\text{Deflect Damage Reduction} * \text{Chance to Deflect})\]
| Offense | Defense | Chance to Deflect | Average Damage Reduction (Assuming 10%) |
|---|---|---|---|
| 40 | 40 | 5% | 4.5% |
| 20 | 40 | 25% | 22.5% |
Don't shoot suppressed TKs at the Construct!
Dodge
The odds for an attack to get dodged is given by this formula:
Formula is unknown!
The current theory is that you can't dodge if you fail the deflect roll.
Miss
Missing occurs when an attack's damage rounds down to 0, like a Peace Keeper using its non-lethal attack on an enemy with <10% HP.
This happens often to units with multi-hit attacks hitting tanks. They roll a deflect which lowers their damage by 90%, then the resistances reduce it below 0.5 damage for a miss.
Immune
When a unit takes 0% damage to a certain damage type is hit by an attack with the matching damage type.
