Description[ | ]
Strategy and Synergy[ | ]
A artifact that specifically supports 
Kunai. One of the better one's that makes Kunai stronger. Not as strong as 
Ninjutsu allows Kunai to get, but it isn't directly harmfull to their strategy like 
Grip Tape.
Picking it up will automatically make all Kunai deal more damage, since everything hit will gain 1 
Fragile. Especially since Kunai are always at the end of the deck, this means all Kunai deal more damage due to the Fragile. This grants Kunai access to 
Power Shard, letting them deal even more damage.
It is possible to keep a high damage spell in one slot until the player gets to the Kunai, but this isn't adviced, since 
Collect Ring will generate more Kunai and will be most often worth more to keep in the slot. Even simply shuffling the deck with only a few Kunai in it is probabaly better. This can be used at the start of the run to deal more damage with common spells. Especially 
Swipe/
Doubletake and 
Coldstone work especially well, since they all are common spells that aren't very intrusive in most other strategies. Coldstone + Swipe/Doubletake + Acupuncture can't carry a entire deck until the End of the run, but dealing 450 dmg for 3 Mana with Coldstone against the first few Bosses is always good.
When found in a deck without Kunai generator's, it won't do that much, since it requires Kunai to work well. Although the player doesn't have to pick up spells to use this artifact. Other common artifacts like 
Knife Belt or 
3D Printer can easily enable Acupuncture and serve as a weaker 
Glassify that cost nothing and applie only 1 Fragile.
