Top 3 things I couldn't do without

So after the second third of our Camino what were the top 3 things I couldn't survive without....so considering there was a large chunk of that time on the 36deg C hot Meseta ..they were:-
1) my hands free trekking umbrella...used every day and made the Meseta more than bearable. There were sooo..many looks, questions and even selfies done with me..definitely a market for them here
2) Voltaren 12hrs ...religiously massaged into our feet (Achilles,calves etc) before and after we walk...soothing and therapeutic ...a key reason for the survival of this no. 1 piece of our equipment
3) Glide/compeed lubricant for feet...initially dubious but was encouraged by a Brisbane lady we met as i was treating blisters on way up to Alto Pedron outside Pamplona....we started using it later and coincidence or not,have had no problems since, the greasiness wasn't a problem
Honourable mentions to the two fundamental backbone of a good way
- smart wool socks (3  pairs)
- merrell mid boots
These have never let me down...only used sandals to walk one.
Ps: and of course Anita is a given number one...always☺
So at the end will do the last 3rd and overall ratings...hmmm going to be hard to split.
