Skulk Emblem [Item Concept]

The Deep Dark needs more loot, as the current new loot as of now isn't that worth to get in the long run.  Here's my thoughts:

Skulk Emblem

This item can be crafted with 6 Echo Shards and 2 Skulk Catalysts around 1 Totem of Undying (Placeholder recipe).

While this item is in your main hand / offhand, when a mob dies within 5 blocks from you, the Emblem absorbs the mob's soul, capping at 3 souls at a time.  Every 10 seconds after obtaining a soul, one gets removed and released back out, screaming as usual.

For each soul you have on you at a time, your XP gain is increased by 33.3%, and your attack damage is increased by 1, both maxing at +100% XP gain and 3 extra damage.

Why does it work like this?

Skulk Catalysts are one of the known ways of obtaining XP fast, and that explains on its own.  The reason why attack damage is increased is to encourage players to use their Emblem for killing mobs, instead of sitting at an XP-Furnace generator for 5 minutes.

This can also be used for PvP, as you would run away, steal a few mobs' souls, and rejoin the fight with +3 damage, and that extra damage can turn the tables for you.

This item could add new strategies to PvP, and it can help with players needing to XP farm for using Level 30 Enchantments.  It also gives the Ancient Cities another use to explore.
