What is the Level-Up Wizard?

The level-up wizard is the step-by-step modal that handles every choice for a new level. It runs at level 1 and at every level after. Each step validates against the ruleset.

Steps on Core SRD 3.5:

1. Class plan. Pick the class for this level. Multiclassing is supported. Classes whose prerequisites you don't meet are listed but disabled.

2. HP. Roll the class's hit die or take the average. Constitution modifier applies automatically per level.

3. Ability score increase. Only on levels 4, 8, 12, 16, 20.

4. Skills. Skill points come from the class formula. Class skills are highlighted; the rank cap is enforced (level + 3 for class skills, half for cross-class).

5. Feats. Standard feats at levels 1, 3, 6, 9, 12, 15, 18. Class bonus feats appear at the levels their class grants them. Each slot is tied to its aptitude pool — only feats tagged for that pool are offered.

6. Spells / powers. For prepared casters (Cleric, Druid, Wizard) you pick which spells go into your spellbook / domain. For spontaneous casters (Sorcerer, Bard) you pick spells known.

7. Review. Final summary of every change. Nothing commits until you click Confirm.

A feat you expected isn't offered — three reasons, in this order:

1. Prerequisite not met. Hover the greyed-out feat — the tooltip explains what's missing.

2. Wrong aptitude. A General feat won't appear in a Fighter Bonus Feat slot.

3. Not in your ruleset. Some feats only exist in extensions like Complete Warrior. Install the extension on your fork.

For mid-campaign characters joining at higher levels, Add multiple levels plans the full path up front and commits in one go.

The engine validates the base, permanent character sheet. Temporary buffs, conditional bonuses (Dodge's +1, Mobility's +4 vs AoO) and activated abilities (Power Attack, Combat Expertise, Smite Evil, Rage) aren't auto-applied. Apply them at the table.
