Plague Bearer's Weapon Swap

Plague Bearar is a persistent skill that can be used to attack.

In version 0.3, automatic weapon swapping during skill use became instantaneous, so I considered equipping a weapon specific to Plague Bearer on the off-hand.

However, persistent skills only check “Which weapon set should this skill activate with?”

When using Plague Bearer with only the off-hand weapon, it forces the outdated manual weapon swap.

Please implement these items separately:
Which weapon set should Reserve be activated with?
Which weapon set should be used when activating the skill?
