Mask of Penumbra Artifact Deep Dive

Mask of Penumbra is Umbra's draw-acceleration artifact. Draw 1 card whenever you summon your first Morsel unit each turn. The cornerstone of Morsel-based Umbra builds.

Basic info

Field Detail
Clan Umbra
Type Artifact
Effect Draw 1 on first Morsel summon per turn

Rating

Tier S (Morsel builds) / Tier B (general Umbra). Critical for Morsel synergy decks.

Strengths

  • Free draw — +1 every turn
  • Deck cycling — reach wincons faster
  • Compounds with Morsel volume — natural fit

Weaknesses

  • Morsel-required — build-dependent
  • Sub-clan mismatch hurts — pure-Umbra preferred
  • Once per turn — not multi-trigger

Recommended usage

  1. Umbra-main builds with Morsel-heavy decks
  2. Ensure 1 Morsel summon per turn
  3. Stack with Pact of the First Armageddon for pure-Umbra

Best builds

  • Umbra (Penumbra) + Underlegion: Morsel + Spore draw chains
  • Umbra + Wurmkin: Consume + Morsel draw optimization
  • Umbra + Melting Remnant: Morsel sacrifice + Reflame double-trigger
