Blood crystal arm (血晶武装 kesshō busō) is an action associated with LoV LRIGs.
To blood crystal arm a SIGNI, put a SIGNI card from the specified Zone underneath 1 of your SIGNI with the same name as that card. For example, to blood crystal arm [hand] one of your Tsukuyomi, Vermilion Familiar, put a Tsukuyomi, Vermilion Familiar from your hand underneath your Tsukuyomi on the field. That SIGNI becomes blood crystal armed (血晶武装状態 kesshō busō jōtai).
- A SIGNI that is blood crystal armed remains so until it leaves the field. When it leaves the field, the cards underneath it are put into the trash by rule-based action.
- A SIGNI that is blood crystal armed remains so even if the card underneath it is removed for some reason.
- The card underneath the SIGNI cannot be arbitrarily put into the trash.
- It is possible to blood crystal arm a SIGNI that is already blood crystal armed. However, effects that trigger whenever a SIGNI becomes blood crystal armed do not trigger, as it is already blood crystal armed.
- If the Zone designated by the blood crystal arm action is the deck (written as blood crystal arm [deck]), search your deck for a SIGNI with the same name as the SIGNI to be armed, put it underneath that SIGNI, and shuffle your deck.
- Other states and currently active effects, such as up/down, freeze, and power-increasing effects remain even when a SIGNI becomes blood crystal armed.
