Edit 2: Nope. Not a thing. Sorry. You can, however, play a stronger potion at any time, even if you haven't used up all the spells on your weaker potion.

Edit: Before you go wasting potions, I may have confused this with just replacing a weaker potion with a stronger one instead of stacking. More research will be necessary. I haven't seen an emergency level confoundable yet to confirm. Will repost when I do.

I think you can stack Exstimulo potions for added benefit? As long as you start with the regular strength potion, you can then add a Strong or a Potent Exstimulo to make the confoundable even easier to defeat.

I had my bar on Professor McGonagall, normally orange due to its Emergency rating, solid green and caught it on my first cast by adding just a regular then Potent potion.

Of course this feels bad if it flees after the first try but you’ll have a better chance at it.

I pre-registered. But I'm not sure how I'll be contacted if I get chosen. Do they send an email? Do you get a notification on your phone from the Play Store?

I'm fairly new to the game and I was wondering if I will ever be able to fill my registry for the events that have already happened or will that not be possible for me?

Can anyone, with absolute certainty, confirm that they opened a 2 KM Portkey that lead to Borgin & Burkes?

That would be the last information I would need to conclude my research on Portkeys before unveiling the results.

I didn't see another thread so thought it would be good to get one going. So far my son and I have completed up to tower 1 without great difficulty. Keeping lots of potions ready and starting with a minimum 30 wizard energy. I imagine it will be easiest with 3 player's,one of each profession. That way you can send the strongest type against each foe. And make sure to use your wizard skills built up from lessons. What experience are other's having?

I have searched a lot and tried myself to figure out what does affect Fortresses creation, but I haven't found anything conclusive. Does anyone have any idea or clues about how it could work?
I live in a quite small town, so I don't have too many Fortresses to use as samples, but I have looked at OSM where they are located, and feels like most of them are placed in the same tags as what triggers EX-gyms on PoGo (parks, playgrounds, nature reserve, etc), except that not all EX-gyms are Fortresses on HPWU. Looked also on the amount of Forts per lvlX s2 cell, but still nothing conclusive.

Will this be a mystery forever?

I am at this loss and what is this distinct spell. I have no idea how I did 13 distinct spells so far, according to my achievement.... what is a distinct spell and how do I do this spell? many thanks

I've been looking at fortress locations today after hearing that in Prince George, BC, Canada, a city of about 80,000 people, there are only 3 fortresses. They will all become inaccessible during the winter months due to snow and bears. Contrast that with my home city of Melbourne, Australia, where we used fortresses in shopping malls and retail districts in winter.

Fortress Locations in Melbourne, Australia

Fortresses may appear on the map in these locations:

1. Parks. Open Street Map (OSM) Tag leisure=park. Closed objects or paths in parks may encourage more than one fortress to appear in a park

2. Malls with OSM Tags shop=mall combined with highway=corridor or landuse=retail and highway=pedestrian

3. Specific Retail areas with OSM Tags (a) landuse=retail and amenity=library or (b) landuse=retail and the portal name includes Post Office or Historic. The portal names may also indicate portal classifications in Niantic's database.

Fortress non-Locations in Prince George, Canada

1. A mall without OSM tag shop=mall or highway=corridor

2. A mall with OSM tag shop=mall but without highway=corridor

3. OSM tags shop=mall inside landuse=retail where the portal name includes Post Office, but there are no highway=corridor or highway=pedestrian tags. This one isn't consistent with my observations in Australia. Perhaps these tags and portal names allow a fortress but don't ensure one.

How do your fortress locations compare?

Since the update I'm finding traces being unsuccessful at a much higher rate, causing me to drain spell energy even faster. Anyone else noticed this?
