No, the reason for this is that no-prayer firecapes are monitored by Jagex, and therefore there is no reason to. When using remote control software there is also a delay, and for no prayer firecapes we need to be tick-perfect, therefore there can be no delays when providing this service. We haven't had any bans or cape removals and have provided 100+ no-prayer firecapes.
No, a bank-pin is not required for this service. You can just leave your account with the gear & inventory setup that our caper will ask from you at the Fight Caves.
You will need around 7.5M OSRS GP for supplies, and you will need to provide purple sweets for the no-prayer firecape service. The amount of purple sweets you will need to provide depends on your Ranged level.
Our caper will discuss the gear required for your no-prayer cape. This is dependent on your stats and Ranged level. If you don't have OSRS GP available for the gear requirements, then in some cases the caper can provide the gear himself.
