Heimerdinger: Champion base stats & armor planning

Heimerdinger starts with 558 HP, 19 armor and 550 attack range in Data Dragon 16.21.1. Use the planner to compare added health and armor in a simple physical-damage scenario.

The model uses positive armor only: effective HP = HP × (1 + armor/100). It excludes penetration, true or magic damage, shields, healing, runes, items with special effects and level growth. Ability names identify the kit; no spell damage is inferred from Data Dragon.

Using this reference

Use Heimerdinger to compare two simple health-and-armor budgets. First leave added health at zero and change armor, then reset armor and try added health. This makes it easier to see what each purchase would change within the displayed physical-damage model.

Keep the scope of that result in mind when looking at another champion. Base health and armor do not include the rest of a kit. The ability list identifies names, while shields, healing and damage interactions would need their own rules before they could support a build recommendation.

One useful comparison

For HP, Heimerdinger is listed at 558, compared with 560 for Annie: a difference of 2. This compares that field in the recorded variants only. Read the other fields before deciding whether the trade-off matters to your use.
