“solo” cleric is a big nono in my opinion, the best thing that you are gonna able to do is to hunt bosses alone (with krivis or PD mainly) but if you want to farm maps I suggest to look at another class, honestly 
That sad (all cleric ARE cleric 2, so I’m discussing rank 3-8)
Diev 3 Druid 3: really nice support, still “ok” DPS for exping solo
Diev 3 Miko 1 PD2: good support and far better DPS
slops: diev 3 is a pain to exp ^^ you basically are gonna go with cafrisun + weapon lvl 5 + ardee dagger + pardoner buff till rank 6 (IMO not so bad, since in reality doesn’t changes anything and you are still double shotting all the exping mobs plus you are gonna have owls for minibosses, but it’s not like an archer ;))
C2 Kriv 3 Druid 2 Taoist: dedicated single target DPS that uses transform for lighting mobs bonus, taoist for lighting etc. You are gonna be a 3 buttons char toon but if u like the dedicated playstile it’s ok
slops: single target DPS, that’s it
Priest 1 Paladin 3 PD Inqui: dex melee char, It’s phisical and Use conviction on the inquisitor wheel to make a “super” aoe rotation. It’s a melee cleric
Also Priest 3 Chaplain 1 Miko 1 inqui 1 could be a nice solo player but I have no idea how it’s play at lvl 300+ in pve contest, honestly.
