As you discuss options, the decision is made for you. A couple of kobolds, apparently late for the party, stumble across yout group. Their surprised yips alert Tartuccio.
"Who is there?! How?!" Tartuccio nearly jumps in the air.
"Here, you fools! Ah, I mean, tribesssmen! Don't lisssten to any liesss they tell you! I ssshall bring you glory, just help me find the relic -- and ssstop them!!!"
Tartuccio suddenly disappears and kobolds scatter in all directions. Several of them turn and attack you. You easily cut through them, but once again, Tartuccio has successfully sacrificed dupes to delay you enough for his escape.
