|Nonno's stats are really good compared to monsters in her tier. In her evolved form, Her HP exceeds 23,000, her Attack is 30,188 and her Speed is set at a generous 335.23. In her ascended form, you trade off stats from Speed into HP and Attack. Her HP in her ascended form hits 24,299, her Attack increases to 30,779 but her Speed falls off to 309.08. Both of these forms are equally good.
Nonno's Bump Combo is a One-Way Laser XL which is exactly like Arthur's and Margarite's Bump Combos. However, Nonno's One-Way Laser XL takes on the fire attribute, which can be extremely helpful in dungeons where you need a strong fire attribute monster. In her ascended form, Nonno gains a secondary Bump Combo, Homing Piercer 4, which fires homing missiles that pierce through enemies.
|Like many other monsters who have ascensions, Nonno's ascension materials are pretty hard to farm for. The materials require you to clear 5 Star Event Dungeons multiple times and hope for a drop. Similar to Arthur, Nonno has the Null Damage Wall ability but just recently, new obstacles have come to NA. These obstacles include Mines, so Nonno may have trouble dealing with them because she has no Flight Abilty.
|Overall, Nonno is a really good monster and is often regarded as a fire attribute Arthur. Both have high stats, the same Bump Combo and ability but Nonno just has the fire attribute. It's entirely up to preference whether to go for the ascended for evolved form of Nonno, both are equally good. The trade-off is ease evolution and increased Speed in her evolved form while having an increased amount of Attack, HP, and a secondary Bump Combo in her ascended form. However, her ascend materials are relatively hard to farm for.
