What PVM grinds are the most important for ironmen?

I'm looking for a list of grinds to go for that are worth it. Things I can think of off the top of my head are:

• dragon defender
• moons
• 2 synapses
• 4 zenyte shards
• dragon warhammer
• royal titans prayers/twinflame
• berserker ring
• imbued heart

Anything that I'm missing from my list? Or is there a wiki page for important ironman grinds to go for?
