Weaving

Weaving is a status effect that lessens the movement speed decrease from being in a cobweb, as well as causing cobwebs to be placed upon death.

Entities with Weaving are less affected by the usual speed decrease that entities suffer from while moving through cobwebs, allowing them to walk through them at 50% speed instead of 25%. Weaving also causes any entities that have the effect to spawn cobwebs in an area around the entity upon its death, making it the only renewable source of cobwebs. 2–3 cobwebs can spawn in a 3×3×3 cube centered on the affected entity. The cobwebs can spawn only on top of existing blocks. These existing blocks must have a full face on the top side, meaning that cobwebs cannot spawn on top of other cobwebs. Mobs affected by Weaving emit web-like particles. When the game rule mobGriefing is set to false, entities excluding the player do not generate cobwebs upon death.

The source of the effects is irrelevant for the purposes of this advancement. Other status effects may be applied to the player, but are ignored for this advancement.
