Heya, just curious about something...
I'm at Keeper's Pledge at the moment, the one time pledge of $100. Due to psychology (and continued support), I'd like to achieve a higher level of Pledge, and I'm curious about how it works (dang you psychology).
If I pledge another $150, atop my original my $100 level, will it take me to Protector's Pledge (which is the $150 level), or to Pathfinder's Pledge, the $250 level?
In other words, is Pledge level determined by highest single donation size, or total donations?
I believe your question is answered if you just go to the upgrade page.
It looks like $150 takes you to the Pathfinder's pledge.
Yes, if you follow the link that Kel kindly posted: https://www.pantheonmmo.com/join/upgrade_keeper/ it will take you to the upgrade page, from there just select the pledge from the drop down box that you wish to upgrade to and an option will pop up to pay the difference and upgrade, if you have any trouble please submit a support ticket and the team will be able to help you further :)
