Worship
Worship is a Watcher uncommon skill that gains 5 Mantra for 2 energy. Mantra accumulates toward Divinity stance, which is entered at 10 total Mantra and grants triple damage on all attacks. Worship provides 5 Mantra in a single card — half the requirement for Divinity. It's a straightforward, efficient Mantra generator with no other effects; pure Divinity investment. Two Worship casts or one Worship plus a Pray can bring you to Divinity threshold quickly.
Worship is the most efficient raw Mantra generator, providing 50% of the Divinity threshold in one play. In Divinity-focused builds, having 2 copies of Worship means a single Worship-heavy turn can get you very close to Divinity activation. The 2-energy cost is the main limitation — spending 2 energy on a non-damage, non-block card requires strong energy generation from Calm cycling or relics. Upgraded, Worship gains 5 Mantra AND 1 energy, making it essentially cost 1 energy while still providing the full 5 Mantra, dramatically improving its efficiency.
