Lich - Drain Life Blood - Pact Node Mana cost bug

[Morfenat]

When you place the blood pact node at the Drain Life Specialization tree that stands “Drain Life no longer costs mana.”
Mana Cost: 0
Current Health Cost Per Second: 10%

But it actually do costs 1 mana point, so it makes impossible to have a necrotic/poison damage filler ability to in the dps rotation while waiting cds & mana back.
And of course, it contradicts it’s own statement.
