Overview
Neither description names a character editor, visual preset menu, or player naming field.
Every Shell has a distinct look together with changes that affect play. It does not say the individual Shell appearance can be manually altered.
Practical details
Names main melee weapons, ranged sidearms, Tarstones, and seals as configurable combat layers. Tarstones can add stats, temporary elemental effects, or new abilities.
Shell progression is also not the same as avatar authoring. Points spent enhancing a particular Shell can be refunded and reallocated for free, allowing to try different combat approaches. Nothing about creating a player biography or changing the underlying Shell model.
Route and choices
The safest terminology is therefore Shell selection, Shell discovery, and loadout customization. Calling it "character creation" without qualification could mislead a player expecting a face-and-body editor. The confirmed customization path is choosing a discovered warrior and combining the supported equipment and progression systems around that warrior.
