You looked at your options and willed the following to appear.

A small wall in the shape of a tent with a small alcove inside of it. The core was placed inside of this alcove. six  Eggs appeared around the dungeon core, a total of 20 plants then dotted the dungeon area, the majority of it around the dungeon core. hidden among the plants four Strangle Weeds, two per entrance, were planted, they swayed with the current, though anything nearby made the plants move.  Four larvae  were also in the plants, they started to eat.

With a total of 170 in reserve you decided to take a gamble,  and put 20 points into the gacha. 

Before we begin, each object in the Gacha is ranked by a tier, 

The tier list goes from highest to lowest
