anyone have tips for the true arena in robobot? so far I`ve found mirror, poison, and sometimes doctor or psy to be helpful.
If you have amiibos and the ability to use them, do not be afraid to. Amiibos are a huge life saver- ESPECIALLY the ones that are official for the game. I recommend starting with hammer and trying to keep it as long as you can. If you lose hammer, use a squid amiibo if you have it as well. It will slightly restore your health at well. I try to make it to haltmann or galacta knight before I use my poison ability. Youtube videos are a lifesaver for finding out ways to cheap out the bosses with hammer, but it still takes practice.
If you have the official amiibos, SAVE THEM until Star Dream Soul OS- you will need maximum tomatoes midfight for that fight because it does NOT give you a break between any of the segments of star dream's battle. If your low on health and it throws you into the final part of the battle, you're most likely going to end up losing unless luck is on your side. I rely mostly on my king dedede amiibo, but the meta knight one works especially well on the final part of the fight. It doesn't matter which you use for the OS fight- I prefer using parasol first- then sword, hammer, and then UFO- UFO being my favorite for the first segment of the final fight if I have it available (meaning I haven't used the amiibo already).
I usually switch to poison for the second segment of the final fight.
(I don't know if you want spoilers, so i'm refraining from saying what the final fight form of star dream actually is).
So sorry for rambling, I play true arenas a lot so i'm good at memorizing strategies. I'm pretty reliant on Amiibos since I can use them as you can see- but I'm sure poison and hammer are your best bets for getting far. Then again it depends on playstyle and preference of ability- I have a friend that prefers ESP and got far with that and didn't do too well with hammer.
