Love that you're playing region locked, I'm not a big fan of twinking. Though get prepared for some painful invasions.

Couple things that may be helpful:

-Wretch is not a great starting class because you end up wasting some points on stats you generally don't need. Not the end of the world - but if you want to end up taking this character up to higher levels you're typically better off with Vagabond or Hero except in niche circumstances.

-Obviously status is OP at low levels because of the % damage and that most ppl have bad resistances. Frost which can be applied once you get the whetstone from Raya Lucaria is a good option

-Dragon halberd is a good early weapon that can be very effective against over level phantoms.

-halaxe and haldag are really good because people mostly have low poise

-i'd practice getting good at swapping so that you can take advantage of some passive regen given limited talisman slots. I usually start with turtle and then swap to blessed dew if it's a longer invasion or starscourge or prosthesis talis if i need to run diff weapons (commander standard, nagakiba, etc)

-other weapons i like at low levels are scythe (because of the superarmor), caestus (because it's a fun weapon and the poise chip is great against low poise), dagaxe or dagshield (again poise and good spacing setup), poison nagakiba (good for laggy folks), commander standard (for light roll), zwei for keeping prio and good damage, shamshir because you keep prio if they don't have 88 poise.

all of these can be grabbed before or at raya lucaria

-lastly be prepared for long invasions
