Brelshaza questions

As title, just reached 1505(+21) a few days ago and now is setting next my goal and plan toward it. I do not care much about alt so I do not plan to hone all or any my alt to 1475 or higher. All in on main.

Is +21 weapon good enough for gate 5/6 normal or it is unreasonable? Also is it much cheaper to get to 1520 on week 2 instead of week 1?

Thank you for your input.

Week 2 will be cheaper, since honing Brelshaza and above gear requires all new materials.
But since ure all +21, you could clear gates 1-4 which alongside the chests could get you a brelshaza relic piece, you couuld technically hone that piece week 1 to get 1520 and do gate 5/6 week 1 if gold isnt a problem to u.

+21 is enough and you will spend a metric ton trying to get to +22 when instead the reset happens with the artifact gear and you get +13’s far far better honing chance.
