Rhino Helmet Farm

[LordYogo]

So I was hunting for Rhino P Helmet for whole weekend. I did around 35 rounds (more T1 than T2 becouse of amount of keys). Needlessly to say I still didnt got one... Theoretically speaking which tower have better chaces of dropping helmet? Counting T1 has 7 items on drop tables (if we count keys  as one item) vs T2 that has 8 items but no keys?

Keys and formas have a way higher drop chance. You possibly will get better results on T2, I don't have the numbers though.

I couldn't find any spreadsheet with current numbers but it must very rare. The prices on warframe.market seem to suggest it. I ran tons of T1 mission and got only one helmet so far.

I ran 25 T1 keys and nothing. I ran 23 T2 keys and got one Rhino helmet bp. Based on this anecdotal evidence, T2 has a better chance for it to drop.
