have 56k gems and f2p, how should i spend this?

some stats:

• ~93m power
  • no idea how old is the server, but highest power based on highest stage is ~500m
• in number 1 guild on server at 8.1B
• on stage 42; mainly cause im not pushing it since i have to manually tap every fight
  • is there reason to rush?
• pets are: elephant, fire dragon, flash
• hero: knight of the end, undead pirate - not really spending much here
• brands: hellhound and gunner

gear:

• durian purple +2
• revival cape purple +2
• guardian ring orange +1
• eagle ring orange
• frostwind horn orange
• proof of glory orange +1

ive been saving up resources for these 'timed growth' events as well.

i use my energy with focus on the travel function, mostly let the energy fill, then do lair for more energy to travel at 100e

any other tips welcome
