Leech

root@maliwan-db:~$ cat description.txt

A Maliwan transfusion grenade built for support rather than raw damage. Its blast is much smaller and weaker than most grenades, but instead of relying on healing tendrils it converts the damage it deals directly into health for the user, making the sustain far more reliable at range or through awkward terrain.

The red text references Samuel Butler's poem Hudibras, which itself echoes Homer's Iliad. In that older usage, a leech is a physician, matching the grenade's healing focus.
