'Haaaaaaaa, Frost it's necessary all these costs are necessary just push through.' Frost sighed as he looked at the rapidly increasing cost of his shopping cart. Wavering slightly with every addition.
"Alright let's put aside 2500DP for emergencies and tonight's festivities, that leaves 28,000 for monsters." With the 2 new floors and finished 3rd floor he had a lot of space to fill.
"Individual purchases can wait; I'll get spawners first. One E-rank frost lizard spawner on the 4th floor's second section, 12,000DP. Another frost dwarf spawner for the 4th floor's mines, 12,000DP and finally since I like them so much let's get another frost goblin spawner for the 3rd floor, 3000DP." Though they were the weakest caste of monsters and provided little in terms of materials they followed orders well and were very cost efficient. Frost couldn't resist buying another one, making for 3 frost goblins spawners in total.
