There was a build before that focused on SPR because there are skills that scaled off the stat.
- [deprotect zone] for -def
- [monstrance] for -def -eva
- [zalciai] for -crit resist
- [hexing] for -mdef
- [stone skin] for + block and ability to block without a shield
- [blessing] for more damage
- [barrier] for +mdef
- [increase magic defense] for + mdef
[deprotect zone] took the 1st hit when it was made to no longer be able to reduce def below 0 giving the skill a hard cap. There was no point going max SPR if monsters only had around 200 def anyway. There is also the fact that there are “reduce armor to 0” debuffs that don’t require stats.
[monstrance] was never reliable as a debuff because the magic circle location was random and disappeared after 1 monster stepped on it.
[zalciai] lasted quite a bit longer in that crit resist could still be lowered below 0 but in the end that followed [deprotect zone] too.
[hexing] reduces mdef via SPR but it isn’t 1:1, it’s -0.3SPR. It wasn’t nerfed directly, rather ridiculously high mdef monsters were introduced. Even if you got 500 SPR, what is -166 mdef in the face of 3k mdef?
[stone skin] is nice but it doesn’t protect against what actually (usually) kills you, magic. It “works” because it “comes with the chaplain”.
[blessing] got buffed, but it is more of a damage skill than “support”. And again, it comes with the chaplain so it works.
[barrier] is a 1:1 increase in mdef per SPR. It is “ok” for the content you get it in which is r6. After that, not so much. It also doesn’t help that it is a zone on the ground (it doesn’t follow you) so if staying in it kills you, it becomes pointless. You are better of relying on the attribute for 40% (is that right? please do correct me if I’m wrong) ranged damage reduction (including magic) that doesn’t scale with stats. It also happens to compete with chaplain so … no.
[increase magic defense] is also a 1:1 increase in mdef per SPR. Unlike [barrier] it is a buff so it is on you for its duration. Sadly it has only 57% uptime and therefore not really reliable. It also competes with the chaplain so … no.
Actual “useful” support comes in invuls. That means completely negating damage. And the cleric has a couple of options for this. This will NEVER fall off (unless IMC introduces buff removal on monsters). They also don’t scale off a stat so any build can use them (hence INT/CON can work). This is also partly (completely) why clerics are broken so it could be up for the chopping block (but IMC won’t say so making it “risky” to build for … not really
).
