Advanced Gen 5 Damage Statistics Guide
Why Damage Ranges Matter
This calculator estimates battle damage for Generation 5 style matches. It focuses on the statistical range, not only one final number. Each attack can land one of sixteen random rolls, from eighty five percent to one hundred percent. That spread makes planning important.
Planning With Modifiers
Use it when you compare move choices. Use it when you test EV spreads. Use it when a small modifier may change a knockout chance. The tool accepts level, move power, attacking stat, defending stat, remaining HP, critical state, same type bonus, type effectiveness, burn, weather, screens, target rules, held items, ability effects, and extra multipliers.
Understanding Results
The result area shows minimum damage, maximum damage, average damage, median damage, variance, standard deviation, one hit knockout chance, half health chance, and hit range. These values help you judge risk. A move with a higher average may still miss an important knockout. A safer move may have a stronger minimum roll.
Roll Logic
Generation 5 calculations use fixed ordering. Base damage is found first. Then modifiers change the result. The random roll is applied across sixteen possible values. This page lists every roll, so you can see each possible outcome.
Input Accuracy
Remember that the calculator depends on your entered battle data. Stat boosts, item boosts, abilities, and weather must already be reflected by your chosen multipliers. Critical hits in this generation use a double damage modifier. Burn usually halves physical damage unless an effect prevents that penalty.
Statistical Review
The statistics section is useful for planning. Standard deviation shows how spread out the rolls are. A low deviation means the damage is stable. A high deviation means the attack has more uncertainty. Knockout chance counts how many of the sixteen rolls reach the target HP.
Probability Notes
Because each roll has equal weight, probability is simple to read. One winning roll means six point twenty five percent. Eight winning rolls mean fifty percent. Sixteen winning rolls mean certainty. This makes range tables clearer than a single damage number during close matchups.
Best Use
This calculator is best used as a planning aid. It does not replace battle rules knowledge. Check unusual mechanics carefully. Then enter the correct multipliers and compare several attacks. Export the report when you need to save calculations for later review, team notes, or matchup testing.
