When you use your point every level in stats it adds to the +XX.

When you add STR points, you get extra non blocked damage.
When you add DEX points, you get a percentage boost on Aim and Evasion.
When you add END points, you get more defense/hp/block rate percentage.
When you add INT points, you get the same thing for STR only with magic attacks.
When you add SPR points, you get more Magic defence/SP/crit rate percentage.

^ Yes he is correct. Take note though that after 25 points in SPR the critical rate boost effects are lower so, best to have 25 points maximum in SPR.
