how long does these spells last?

With the conjure candles that isn’t necessary because during the incantation for conjure candles you ask spirit that what you ask for “shall never reverse or dissipate” as it says in the booklet, so you don’t need to do anything extra to make the spell last longer.

Spelled candles work for and they work fast but like I said the spells are short lived. They don’t always work but the work more often than they don’t. I didn’t know about adding personal effects. I would consider trying that. Any specific instructions? Thanks.

If you want longer results with your spells you need to add your personal concerns to you candles. Examples of this would be: your hair, fingernails, toe nails, or spit. Adding these things to your candles will bind the spell to in a way that will surpass just chanting alone. *Do not use your blood.

My spelled candle results are immediate but only last days or a couple weeks at most. Conjure takes a little longer and lasts or manifests takes a little longer. But usually more stubborn situations.

Just keep layering

I feel like everyone is different. Some ppl require couple weeks , some last months, depending on your blockages. I would suggest just making sure your roads are open to keep receiving the work you put in . And protection of your work aswell
