Ah, that's the teamskill between Barbara and Nidhogg, but it hasn't been implemented yet, that will only happen with the next update.

The teamskill is (unlikely to change but who knows!): Change the Leader Skills of specific Monsters from "Oath of Blood" and "Bloodthirsty Dragon King - EX" to "Bloodthirsty Alternation". Earth Dragon and Earth Beast Attack x 3.5, HP x 1.5; 5% of total HP will be deducted every Round. 10% of Damage dealt to enemies by Dragons and Beasts will be converted to HP. The max HP Recovery is 50% of Summoner's total HP (no superimposing; Damage dealt by Active and Leader Skills will not trigger the effect). If the HP converted is larger than Summoner's total HP, for every 12% exceeded, turn 1 random Runestone into Earth Runestone after the Round, to the max 4 Runestones (no superimposing).
